Abstract: The dual purpose track comprises a unitary elongated body having a longitudinal axis and a raised center section extending along the axis from one end to the other. The center section includes a flat base with downwardly tapering sides terminating in laterally outwardly extending flanges. The flat base which extends along the longitudinal axis is provided with longitudinally spaced apart elongated slots, as an example, spaced every four inches, which extend lengthwise along the axis. Each slot is configured to receive either the head of the bolt of a wheel chock used to retain a dirt bike along the floor of a trailer or a tie down fastening device. A strap is connected between the tie down device and the handle bar of the dirt bike to assist in retaining the bike in a fixed position. Thus, the track serves two purposes, namely, it holds the wheel chocks and the anchoring devices for the straps.
